EDWIN BOYCE, OF PIN BLUFF,

Application led June le,

To all tls/10m 'it may concern:

. Be it known that l, ,lunwrzv Boron, a citizen of the United States,residing at Pine `Bluff, in the county ot Jefferson and State ofArkansas. have invented certain new and useful Improvements in Rims andTires; and I do declare the following to be ay full7 clear, and exactdescription 'of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.l

This invention relates to an iinprovedisectional tire rim especiallyadapted for use on automobile wheels.

The principal object ot the invention is to generally improve upon rimsof this class by providing one ot' extreme simplicity and durabilitywhich is practical, inexpensive, and such in construction that it iscapable of being applied on various kinds' of wheels withoutrequiringextensive alteration.

More specifically, it is an object of the invention to provide a tirerim having a. channel for reception4 of a circumferential rib on a secial type of pneumatic tire.

ther objects and yadvantages of the invention will be apparent duringthe course of the following description.

In the accompanying drawings forming a part of this specification and inwhich like numerals are employed to designate like parts throughout thesame:

Figure l is a transverse sectional view through the telly ot a wheelshowing the improved riin thereon and disclosing the manner in which thespecial tire is asso ciated therewith.

Figure 2 is ay view like Fig. l showing the retaining rib of the tirepositioned approximately at the center ot the wheel telly, the rim beingmodified to accommodate this,

Figure 3 is substantially identical with Fig. l. one ot the detailsbeingr omitted.

Figure 4: is a view like Fig. 2 wherein the rim is applied upon a commonunaltered wheel telly.

Figure 5 is a view substantially the same as Figs. l and 3 showing aslightly' modified form ot' tire.v

Figure 6 is a. detail section showing theinvention applied upon a. diskwheel.

Broadly speaking, the rim shown in the several figures of the drawing iscomposed of a. pair of ring-like sections, one of which is designed torest aga-inst the 'telly of an automobile wheel so that a portionthereof' 1921. Serial No. 477,509.

extends beyond the telly, this section being formed with acircumferential angular shouldered portion between its edges and havingone edge bent to provide ra stop flange resting against one side of thewheel telly. .the other rim section having one edge engaging this sto-pflange to space it away `trom the flange and shouldered portion tonovide a channel for reception ot an an clioring ril: on the specialtire used in conH nection with this rim.

It may be conveniently mentioned here that the torni orf rim disclosedin l, 3 and 5 is identical and a. description ot Fig. l will suflice'for the other two figures. There-tore, by confining attention to Fig.l. it will he seen that the reference charac-v ter l designatesgenerally one ofthe ringlike rim sections while 2 refers to thecomplemental Section. As shown, the first named rim section is adaptedto rest upon the ii'elly F o'tl an automobile wheel. The portion 3 ot'this rim section l is curved tlansil'ersely and is seated in a trans\ersely curved recessed portion 'formed in the outer periphery ot theaforesaid Jtelly. rl`he outer free edge of' the portion 2l of the rimsection is. extended beyond the inner vertical taz-cof the telly. 'lheintermediate portion ol the rim section is bent inwardly and thenlaterally outward as at 5 to provide what may be. conveniently termed anangular shouldered portion which is intended to be received in a groove(l in the wheel telly which is shaped to receive it. The edge orremaining portion ot' this rim section adjacent the shouldered. part is,dirccted laterally inward to provide a stop flange (3 and this flangeis intended to rest against the inner vert-ical side of the wheel telly.The stop flange o is t'ormcd at cir.- cumierentially spaced points withopenings which register with transverse holes formed in the wheel tellyto permit passage ot the retaining bolts S). The second rim section 2has its outer half shaped as at 7 to conform to a part of a tire againstwhich itl bears. '.lhe inner edge of the inner halt ol" this riinsection is directed laterally as at 8 and this edge bears against thestop flange to Space the two rim sections apart to provide a channelbetween the central portion ot the riin section 2 and the shoulderedintermediate portion ot the rim section l to acconnnodate thecircumferential anchoring rib on the special pneumatic tire T. ln theYtorni et' the invention now under consideration, the anchoring rib ofthe tire is disposed adjacent the inner vertical face of the wheeli'elly and the shouldered part of the rim section i is disposed in a,position to cconimodate the rib when it is at 'this point. Although itis not essential, an endless reinforcing member of channeledcross-section is fitted upon the anchoring rib of the tire and iw.clamped between the rim sections when the nets on the aforesaid boltsare tightened. llt may be stated here that the second named rim section2 is also equipped With openings to accoiinnodate the bolts. It may alsohe stated here that the .two beads-B ofi which the anchoring rib iscomposed are designed at fi. to provide an .interlocking conneo Thisconstruction tion betweenthem. guards against accidental separation ofthe beads.

irecting attentionfnow to Fig. 3, it will be seen, as before stated,that this is substantially identical with the figure just de scribed andthe'same reference characters used in Fig. '1 are 'also used here todesignate like parts. The only difference be'- twcen the tivo'oures'under consideration is 'that the supplemental reinforcing and retainingmember- 1Q is omitted 'from Fig. 3. Attention may. also be logicallydirected to Fig. '5a here sinse this figure is l11 Wise identical withthe two figures already referred to with the exception 'that the beads Eof the tire Vi" are reinforced ir; imbedding Wire or the like thereinand the special interlockingl connection bc tween them is entirelyeliminated. As there I are no other differences, the same referencecharacters already'used will also apply to this figure.

Coming 4novi7 to Fig. 2, it will be seen that the reference character ladesignates generally the inner rim section While 2 designates thecompleinental outer rim section which coacts therewith. The portion 3 ofthe rim section first mentioned is like- Wise slightly curvedtransversely and the free edge thereof projects a considerable distancebeyond the inner vertical side ot' the Wi'ieel telly F. The intermediateportion oit this rim section is bent laterally inward at da and thenlaterally outward as at to provide an angular shouldered portion whichis received inthe comparatively large recess R formed lin the peripheryot' the aforesaid Wheel felly Ff. The opposite -edge of the rim sectionunder consideration is directed laterally inward as at 6** to pro-Uvvide .a stop flange which rests againstthe outer face of the r'eiy ofthe Wheel. '.lhe

-rim section 2E has the portion 7u shaped to contact the casing C of thespecial pncumatic tire, and has its inner edge 8 directed laterally asshown to bear against the stop flange 6a to space the two rim sectionsandto provide a channel between the aforesaid angular shouldered portionand' [the angularly bent central portion l1 of the .rim section 2a. Asbefore' described. this chan-- nel is intended to accommodate thecentrally n disposed anchoring rib B of the casing.

Closely related to that 'form of the .invention just described. is theform shown in Fig. 1l. By directing attention to this figure it will beseen that the rim sections l" and 2b are identical with the rim sectionsdescribed in Fig, 2. Tliere'forex no further description et thesedetails is thought lnecessa'ry, The anchoring rib of the pneumatic tirehowever is composed of beads' which are not connected by the especialjoint and this rib centrally disposed for vreception in, the ren? rallydisposed channel provided between the tire rim sections. The felly F2 ofthe wheel simply has .itsy periphery beveled from edge 'to edge insteadof being recessed as shown inthe already described figure.

Drectingatten-tion ASnally to the other it to be' used on different'kinds of wheels without requiring extensive alteration. Inasmuch as therim is composed of easily separable sections, it will be seen that thetire can be easily and read-ily removed or applied. ln practice, the.shouldered ring like rimsection may belsecured to the Wheel so as topermit it to remain in position. While permitting the remaining rimsection to be remo-ved to permit removal of a damaged tire andsubstitution of a good tire.

By carefully considering* the description in connection with. thedrawing, persons familiar with devices oit' this class will doubtless beable to obtain a` clear understanding of the invention. Therefore, amore lengthy and detailed description is deemed unnecessary.

Since probably the best results may be obtained with the-constructionand arrangement herein shown and'described, this is taken as thepreferred embodiment of the invention. Howe-ver, l wish it to beunderstood that mino-r changes coming Within the scope of the inventionas claimed may he resorted to if'desired.

l claim:

A tire rim comprising a pair of ring-like `rim sections, one of which isdesigned'tobe' side of the felly, said one rim section being providedbetween its edges with a circumferentially extending angular shoulderedportion and having its opposite edge drected laterally inward to providea stop flange for engagement with the outer side of theaforesaid felly,the other ring-like rim section being ,spaced from said flange andhaving its inner peripheral edge directed laterally and bearing againstthe flange, the outer edge of the second rim seo.

f tion being' extended beyond the telly and being spaced` from theaforesaid shoulder to provide a channel for reception -of the rib on a.special tire, and bolts passing through said riin seetio'ns and telly tohold the rim on the latter and to 'tightly clamp the aforesaid ribbetween the rim sections. l

1n testimony whereof I have hereunto set my hand. EDWIN BOYCE.
